Chain Thru by Kreis Magic
Item Number: SP4572
A small chain, a nut, and bolt are given to a spectator. The nut and bolt have hole drilled through them for the chain to pass through. The spectator is asked to thread the bolt through the nut and then place the chain through the hole. The spectator is then asked to turn the bolt and thread it further through the nut. The chain won't allow it! The spectator can not make it turn. The magician then takes the chain, nut, and bolt back from the spectator and threads the bolt on thru!! This effect happens right in front of the spectator's eyes!
Includes Instructional CD-ROM containing both a performance and exlplanation of the effect.
